Scope

Scope: The standard specifies the model specifications, product representation methods, product structure, technical requirements, test methods, acceptance rules, marking, and packaging of copper core mineral insulated prefabricated branch cables with a rated voltage of 0.6/1kV (Um=1.2kV). The standard applies to prefabricated branch cables used for lighting circuits and other similar purposes in tunnels and bridges, with a rated voltage of 0.6/1kV (Um=1.2kV) and a copper core mineral insulation power supply trunk line. Main technical content: Part 1: Technical requirements for 750V rated voltage mineral insulated prefabricated branch cables 6.1 Cable 6.1.1 Cable body quality requirements The cable body shall comply with the quality requirements of GB/T 13033.1 and T/HSXLXH001-2021. For products with halogen-free and low-smoke combustion characteristics, the cable body shall comply with the test requirements of GB/T 17650.2. The measured pH value shall not be less than 4.3, and the conductivity shall not exceed 10 μS/mm; the smoke transmittance shall not be less than 60%. 6.1.2 Configuration of cable specifications 6.1.2.1 The main and branch cables selected in the same group of mineral insulated prefabricated branch cables shall generally be the same. The parameters such as the specifications and length of the main cable, the number of branch cables, and the positioning and tolerance of the branch connection center on the main cable axis shall be manufactured according to the user's technical requirements. Unless otherwise specified, the length of each branch cable shall not exceed 3m. 6.1.2.2 At the branch point of a multi-core main cable, each core of the branch cable shall only be allowed to connect to one branch cable; at the branch point of a single-core main cable, two or fewer branch cables shall be allowed to connect. Unless otherwise specified, the direction of the outlet of all branch cables shall be the same. 6.1.2.3 When the main c
